Or all the diodes down the side that was left :-)Too much hormone treated meat.
Too much Monsanto veggies.
Too old and outdated constitution.
A crazy problem, as you Yanks use to say......There is no God, and God never existed.

Language games aside, it would be interesting to know where the magic smoke was leaking from.

As for Datacenter functionality in the face of a power outage? I strongly suspect that that datacenter is built on spec to be able to operate for <x> time in an outage. Since <x> is a real world measurement bounded by cost, <x> is going to be a modest number. Air conditioning systems for a facility are going to eat up a LOT of power generating capacity. At <y> % of remaining capacity on the system, the AC is probably powered down, and then after a few minutes, hardware is brought down. Cascading, controlled failure.

There may well be another consideration that happened. Generator for the datacenter may well have been adequate, if just the datacenter went down. However with the large area affected, decisions may have been made that the power from the generator was more useful elsewhere. It took the campus over two weeks to place all power back on the utility mains!

A loud electrical explosion in the center of the UC Berkeley campus Monday night – apparently caused by a copper theft – ignited a fire, left four people with injuries, forced a campus evacuation and left about 20 people stuck in elevators.

I know very well the data center, as was one of the Project managers responsible for moving systems and servers around campus to the new installations end of 2005 and 2006 I believe - well they were new then, and the best data center I have seen.

How ever, thieves of copper wire in the states? Thought that was only here in São Paulo (Brasil) that idiots did those things, and even with lines with current flowing. So every now and then, you read about a few chared bodies found in manhole access in the city, where they thnk they can just cut a few 15kv lines out (connected) and they will live to enjoy the spoils.

Yea,the idiots around the world are all the same. Shame to hear about this in the Berkley área where there are suppose to be above average of educated population, and would consider thieves with a little over a above knowdlege of danger.

The outage this thread refers to occurred in October 2013. Recovery from that episode is long since complete. More recent, short-term outages are discussed in the Panic Mode threads in the Number Crunching Forum.Donald
